Lyerla, who left the Oregon team last year over "personal reasons," was busted in Lane County, OR. after officials saw the 6'5", 238-pounder "snorting what appeared to be a white powdery substance" in a parked vehicle.
The 20-year-old later admitted to using and possessing cocaine. Authorities reportedly agreed to meet Lyerla back at his house to continue the investigation, but once they got there he "ran from the vehicle into a nearby apartment."
Lyerla was arrested when he emerged from the place later on.
The player was set to be the starting tight end during the 2013 season before he left the Ducks on October 6.
